Dr David Opar completed a Bachelor of Applied Science (Human Movement) at RMIT University in 2008. Dr Opar commenced his doctoral thesis (PhD) in the area of hamstring strain injuries at the Queensland University of Technology in 2010 under the supervision of A/Prof Anthony Shield. In 2013 Dr Opar joined ACU as a Lecturer in the Discipline of Exercise Science in the School of Behavioural and Health Sciences. Currently, Dr Opar is the Director of the Sports Performance, Recovery, Injury and New Technologies (SPRINT) Research Centre. In addition, Dr Opar is also the Injury Research Program Lead for SPRINT.
The Injury Research Program in SPRINT is a world leader in hamstring injury research, conducting projects that cover a number of disciplines in the field of exercise science. These projects encompass lab-based research all the way through to applied and field-based work. Dr Opar and his team are in close consultation with professional sporting codes both nationally and internationally to deliver evidence-based prevention and treatment strategies for their athlete group. From his research, Dr Opar also co-invented the NordBord, a field measure of eccentric hamstring strength that is now used by sporting teams across the world.
